Ultraschnelle zeitaufgelöste Absorptionsspektroskopie im weichen Röntgenbereich
… ausschließliche Röntgenröhren in der Röntgenspektroskopie benutzt. (Parratt, 1938). In den 50er Jahren wurden die ersten Synchrotrons gebaut und für die Spektroskopie im Röntgenbereich angewendet. (Blocker et al., 1950). Die auch noch heute verwendeten Techniken wurden zum ersten Mal 1948 …

Ultrafast linear and non-linear spectroscopy : from biological light-receptors to artificial light-harvesting systems
In the experiments presented in this work, linear and non-linear femtosecond time-resolved spectrsocopy were applied to investigate the structure-function and functiondynamics relationship in biological and artificially designed systems. The experiments presented in this work utilize femtosecond …

Frequency-resolved ultrafast dynamics of phonon polariton wavepackets in the ferroelectric crystals LiNbO₃ and LiTaO₃
During this work I built a four wave mixing setup for the time-resolved femtosecond spectroscopy of Raman-active lattice modes. This setup enables to study the selective excitation of phonon polaritons. These quasi-particles arise from the coupling of electro-magnetic waves and transverse optical …
